According to a release from the state Department of Transportation, crews are preparing to reduce the four-lane, divided highway to a single lane in each direction by Monday.

Department spokesman J.P. Gillach said Thursday that, "right now it's just intermittent lane closures all over the place."

He said eastbound lanes will be reduced to one at Minnesota Highway 24 in Clear Lake to Sherburne County Road 17. On Friday, the westbound highway will be reduced to one lane at Lakeshore Drive in Big Lake west toward Clear Lake.

"Beginning (Friday) morning, the westbound side will begin closing it to a single lane...toward Clear Lake," Gillach said.

All lanes will be reopened in October. Until then, Gillach affirmed drivers should be extra cautious because the lane shifts will change frequently.

"They're just going to be opening and closing (lanes) as they see fit," he said.

People will still be able to access businesses along Highway 10 during construction.
